(Cl. 21S-29) 16 Claims.

This invention relates to a machine for dispensing and for applying toan article such as a package, adhesive strips or sheets, for example,normally tacky or pressure-sensitive adhesive tape sold under thetrade-mark Scotch.

Prime objects of the invention are to provide a machine which shallembody novel and improved means for dispensing pieces of tape ofpredetermined length into a predetermined position to be engaged by aportion of an article, such as a package, upon movement of the latter inone direction, and means operable by and upon said movement of saidarticle for applying said piece of tape to the article; and to providesuch a machine wherein the last-named means shall also actuate the meansfor dispensing the tape, whereby the machine shall be simple andinexpensive in. construction and operation and shall be reliable anddurable.

Another object is to .provide such a machine in which all of the motivepower necessary to operate it in normal use is supplied by the movementof the articles that are taped or sealed.

Another object is to provide a machine of this character which can bemanually operated by a relatively unskilled operator and with a minimumof attention and physical effort.

A further object is to provide in a machine of the general characterdescribed novel and improved means for withdrawing in successionpredetermined lengths of tape from a roll or strip, ior severing piecesof the tape from the roll or strip, and for projecting and holding thesevered pieces in position to be engaged by an article to which thepiece of ltape is yto be applied.

Other objects, advantages and results of the invention will be broughtout by the following description in conjunction with the accompanyingdrawings in which Figure 1 is a top plan view of a gummed tapeapplicator embodying my invention, with portions broken away and shownin section for clearness in illiistration. l

Figure 2 is a Vertical sectional view on the line 2 2 of Figure 1.

Figure 3 is a transverse vertical sectional View one end of a package orbox having a piece of adhesive tape applied thereto, showing the man-lner in which themachine of the invention applies a piece of adhesivetape.

Specifically describing the illustrated embodiment of the invention, thegummed tape applier includes a. case A that may be mounted on anysuitable support in any suitable manner, but is shown as set into a holeI in the top of a table or like support B. The casing has a top Wall 2disposed slightly above the top side of the support B and having anopening 3 through which the tape to be applied is projected and anapplier forthe tape is operated.

Within the casing are suitable supports, in the present instance rollers4, for a roll C of adhesive tape, the rollers being `shown as mounted oncap screws secured in bosses 5 in the casing, the heads 6 of the capscrews serving to hold the roll of tape on the rollers between saidheads and the ends of thebosses.

One type of adhesive tape with which my applier may be utilized is whatis known as Scotch tape which generally comprises a strip of crepepaper, Cellophane, or the like to one side of which is applied anormally tacky or pressure-sensitive adhesive. Tape can be vunwound fromthe roll Without transfer or oisetting of the adhesive and the adhesivemay be caused to adhere to a surface by simple application of pressureand Without activation of the adhesive as by water, solvents or heat.The strip 'I of adhesive material is unwound from the roll C and passesdownwardly and then upwardly around a guide roller 8 and between a guidespring 9 and a block I0, whereby the tape may be guided and pulledupwardly through the opening 3 in the top wall of the casing. "Theroller 8 is mounted on afstid II and is held thereon by a cap screw I2.The spring 9 is mounted on a stud I3 and the block IIJ is mounted on anangle bracket I4 which is secured byfscrews I5 to one wall of thecasing. Within the casing is also arranged a means generally designatedD for feeding the strip 1 of adhesive material so as to locate the freeend portion thereof in a predetermined position to be engaged by anarticle such as a package or box E upon movement of the latter in onedirection as shown by the arrow in Figure 2. Cooperating with thefeeding means D is a means F for severing a piece of the adhesivematerial from the strip, and means Galso is provided for applying thesevered piece of adhesive material to the box E. As shown, preferablythis means G also servesmas the actuator for the feeding means D.

The feeding means comprises a carrier I 6 which is in the form of a flatbar and has a longitudinal slot I1 through which passes the stud I I sothat the carrier is slidably reciprocable. Oe

end of the carrier has a head I3 which at its lower limit of movement ispressed into adhesive contact with the strip 1 at the side thereoi'opposite the block I0 and during its upward movement pulls the stripfrom the roll C. At its upper limit oi' movement the head i3 holds thefree end of the strip 1 in position to be engaged by the box E.

The means for actuating the carrier I5 includes a gear I9 mounted on astud 20 in the casing and rigidly connected to a crank arm 2| which ispivotally connected at 22 to the carrier I6. Meshing with the gear I3isv a gear segment 23 which rotates about a stud '24 and is rigidlyconnected to the hub 23 of a bifurcated presser lever 23 between thearms of which is a presser' roller 21. The lever 23 normally isinfluenced by a spiral spring 23 so as to locate the roller 21`injuxtaposition to and at the side of the free end ofthe strip 1 oppositethat against which the box E is moved. A stop stud 23 limits themovement of the lever 28 under the influence of the spring 28.

applied along the top of the casing A in the direction of the arrow asshown by solid lines in Figure 2 whereupon the adhesive tape is pressedbetween the roller 21 and the end of the box so that the tape isadheslvely attached to the box. Then the operator continues to move thebox in the same direction against the influence of the spring 23 whichpulls the piece of. tape oil' the head I8 o! the carrier and causes theroller 21 to be moved by and with the box until the roller is forceddownwardly through the opening 3 as shown by dot and dash lines inFigure 2. At the same time, the roller rolls over the piece of adhesivetape so as to securely attach the latter to the box.

During this operation, the carrier i6 has been the lever 3i! is heldagainst movement by engagement of a roller 31 on the lever 33 with astop block 38 on the carrier, but when the carrier reaches its lowerlimit o! movement, the block 3B is moved out of abutting relation to theroller 31 so that the rolle'.` may swing above the block and permitmovement of the lever 30 under the influence or the spring 3l in such amanner as to withdraw the knife blade from the cutting block and thestrip as shown by dot and dash lines in Figure 2. Movement of the knifelever is limited by engagement with the stud I3. Then upon movement ofthe carrier upwardly, the lever 30 is held in its inoperative positionby engagement of the roller 31 with the opposite side of the stop block33 until the carrier has reached its uppermost or normal-position,whereat the block is out of abutting relation to the roller 31 so thatthe knife lever 33 may be swung by the spring 35 into operative positionwith the blade 32 entering the slot of the block 33 so as to cut thestrip and sever a piece of predetermined length therefrom as shown bysolid lines in Figure 2.

Having thus described my invention, what I claim is:
